摘 要: 采用部分相干光的传输理论,推导出了部分偏振高斯-谢尔模型光束传输的3×3阶交叉谱密度矩阵的解析表达式。与其傍轴传输相比,纵向场成分的出现不仅改变了光强在横截面上的对称性分布,还对部分偏振高斯-谢尔模型光束的相干性质和偏振性质产生重要影响。 By using the propagation theory of partially coherent beams,the analytical expression of the 3×3 dimentional cross-spectral density matrix for partially polarized Gaussian Schell-model beams is derived.Compared with the paraxial propagation cases,the appearance of the longitidinal component of the incident field not only changes the symmetric distribution of the optical intensity but also has an immportant influence on the coherence and the polarization characteristic of the beams.
